DETAILED DESCRIPTION

Field crops are bred through techniques that take advantage of theplant's method of pollination. A plant is self-pollinating if pollenfrom one flower is transferred to the same or another flower of the sameplant. A plant is cross-pollinated if the pollen comes from a flower ona different plant.

Plants that have been self-pollinated and selected for type for manygenerations become homozygous at almost all gene loci and produce auniform population of true breeding progeny. A cross between twohomozygous plants from differing backgrounds or two homozygous linesproduce a uniform population of hybrid plants that may be heterozygousfor many gene loci. A cross of two plants that are each heterozygous ata number of gene loci will produce a population of hybrid plants thatdiffer genetically and will not be uniform.

Sorghum plants (Sorghum bicolor L. Moench) are bred in most cases byself-pollination techniques. With the incorporation of male sterility(either genetic or cytoplasmic) cross pollination breeding techniquescan also be utilized. Sorghum has a perfect flower with both male andfemale parts in the same flower located in the panicle. The flowers areusually in pairs on the panicle branches. Natural pollination occurs inSorghum when anthers (male flowers) open and pollen falls onto receptivestigma (female flowers). Because of the close proximity of male(anthers) and female (stigma) in the panicle, self-pollination is veryhigh (average 94%). Cross pollination may occur when wind or convectioncurrents move pollen from the anthers of one plant to receptive stigmaon another plant. Cross pollination is greatly enhanced withincorporation of male sterility which renders male flowers nonviablewithout affecting the female flowers. Successful pollination in the caseof male sterile flowers requires cross pollination.

Sorghum is in the same family as maize and has a similar growth habit,but with more tillers and a more extensively branched root system.Sorghum is more drought resistant and heat-tolerant than maize. Itrequires an average temperature of at least 25° C. to produce maximumyields. Sorghum's ability to thrive with less water than maize may bedue to its ability to hold water in its foliage better than maize.Sorghum has a waxy coating on its leaves and stems which helps to keepwater in the plant even in intense heat. Wild species of Sorghum tend togrow to a height of 1.5 to 2 meters, however in order to improveharvestability, dwarfing genes have been selected in cultivatedvarieties and hybrids such that most cultivated varieties and hybridsgrow to between 60 and 120 cm tall.

Hybrid Development

The development of Sorghum hybrids involves the development ofhomozygous inbred lines, the crossing of these lines, and the evaluationof the crosses. Pedigree breeding methods, population breeding methods,or the creation of double haploids can be used to develop inbred linesfrom breeding populations. Breeding programs combine desirable traitsfrom two or more inbred lines into breeding pools from which new inbredlines are developed by selfing and selection of desired phenotypes. Thenew inbreds are crossed with other inbred lines and the hybrids fromthese crosses are evaluated to determine which have commercialpotential.

Pedigree breeding starts with the crossing of two genotypes, each ofwhich may have one or more desirable characteristics that is lacking inthe other or which complement the other. If the two original parents donot provide all of the desired characteristics, other sources can beincluded in the breeding population. In the pedigree method, superiorplants are selfed and selected in successive generations. In thesucceeding generations the heterozygous condition gives way tohomogeneous lines as a result of self-pollination and selection.Typically, in the pedigree method of breeding five or more generationsof selfing and selection is practiced. F₁ to F₂; F₂ to F₃; F₃ to F₄, F₄to F₅, etc.

Backcrossing can be used to improve a line. Backcrossing transfers aspecific desirable trait from one source to another source that lacksthat trait. This can be accomplished for example by first crossing asuperior inbred (A) (recurrent parent) to a donor inbred (non-recurrentparent), which carries the appropriate genes(s) for the trait inquestion. The progeny of this cross is then mated back to the superiorrecurrent parent (A) followed by selection in the resultant progeny forthe desired trait to be transferred from the non-recurrent parent. Afterfive or more backcross generations with selection for the desired trait,the progeny will be heterozygous for loci controlling the characteristicbeing transferred, but will be like the superior parent for most oralmost all other genes. The last backcross generation would be selfed togive pure breeding progeny for the gene(s) being transferred.

Sorghum varieties are mainly self-pollinated; therefore,self-pollination of the parental varieties must be controlled to makehybrid variety development feasible. A pollination control system andeffective transfer of pollen from one parent to the other offersimproved plant breeding and an effective method for producing hybridseed and plants. For example, the milo or A₁ cytoplasmic male sterility(CMS) system, developed via a cross between milo and kafir cultivars, isone of the most frequently used CMS systems in hybrid Sorghum production(Stephens J C & Holland P F, Cytoplasmic Male Sterility for HybridSorghum Seed Production, Agron. J. 4620-23 (1954)). Other CMS systemsfor Sorghum include, but are not limited to, A₂, isolated from IS 12662c(Schertz K F, Registration of A ₂ T _(x) 2753 and BT _(x) 2753 SorghumGermplasm, Crop Sci. 17: 983 (1977)), A₃, isolated from IS 1112c orconverted Nilwa (Quinby J R, Interactions of Genes and Cytoplasms inMale-Sterility in Sorghums, Proc. 35th Corn Sorghum Res. Conf. Am. SeedTrade Assoc. Chicago, Ill., pp. 5-8 (1980)), A₄, isolated from IS 7920c(Worstell et al, Relationship among Male-Sterility Inducing Cytoplasmsof Sorghum, Crop Sci. 24:186-189 (1984)).

In developing improved new Sorghum varieties, breeders may use a CMSplant as the female parent. In using these plants, breeders attempt toimprove the efficiency of seed production and the quality of the F₁hybrids and to reduce the breeding costs. When hybridization isconducted without using CMS plants, it is more difficult to obtain andisolate the desired traits in the progeny (F₁ generation) because theparents are capable of undergoing both cross-pollination andself-pollination. If one of the parents is a CMS plant that is incapableof producing pollen, only cross pollination will occur. By eliminatingthe pollen of one parental variety in a cross, a plant breeder isassured of obtaining seed of uniform quality, provided that the parentsare of uniform quality and the breeder conducts a single cross.

In one instance, production of F₁ hybrids includes crossing a CMS femaleparent with a pollen-producing male parent. To reproduce effectively,however, the male parent of the F₁ hybrid has a fertility restorer gene(Rf gene). The presence of an Rf gene means that the F₁ generation willnot be completely or partially sterile, so that either self-pollinationor cross pollination may occur. Self-pollination of the F₁ generation toproduce several subsequent generations ensures that a desired trait isheritable and stable and that a new variety has been isolated.

Promising advanced breeding lines commonly are tested and compared toappropriate standards in environments representative of the commercialtarget area(s). The best lines are candidates for new commercial lines;and those still deficient in a few traits may be used as parents toproduce new populations for further selection.

A hybrid Sorghum variety is the cross of two inbred lines. The hybridprogeny of the first generation from a cross of two inbreds isdesignated F₁. In the development of hybrids the F₁ hybrid plants aresought. The F₁ hybrid is more vigorous than its inbred parents. Thishybrid vigor, or heterosis, can be manifested in many ways, includingincreased vegetative growth and increased yield.

The development of a hybrid Sorghum variety involves five steps: (1) theformation of “restorer” and “non-restorer” germplasm pools; (2) theselection of superior plants from various “restorer” and “non-restorer”germplasm pools; (3) the selfing of the superior plants for severalgenerations to produce a series of inbred lines, which althoughdifferent from each other, each breed true and are highly uniform; (4)the conversion of inbred lines classified as non-restorers tocytoplasmic male sterile (CMS) forms, and (5) crossing the selectedcytoplasmic male sterile (CMS) inbred lines with selected fertile inbredlines (restorer lines) to produce the hybrid progeny (F₁).

Because Sorghum is normally a self-pollinated plant and because bothmale and female flowers are in the same panicle, large numbers of hybridseed can only be produced by using cytoplasmic male sterile (CMS)inbreds. Flowers of the CMS inbred are fertilized with pollen from amale fertile inbred carrying genes which restore male fertility in thehybrid (F₁) plants. Once the inbreds that produce the best hybrid havebeen identified, the hybrid seed can be reproduced indefinitely as longas the homogeneity of the inbred parents is maintained.

A single cross hybrid is produced when two inbred lines are crossed toproduce the F₁ progeny. Much of the hybrid vigor exhibited by F₁ hybridsis lost in the next generation (F₂). Consequently, seed from hybridvarieties is not used for planting stock.

Hybrid Sorghum can be produced using wind to move the pollen.Alternating strips of the cytoplasmic male sterile inbred (female) andthe male fertile inbred (male) are planted in the same field. Wind movesthe pollen shed by the male inbred to receptive stigma on the female.Providing that there is sufficient isolation from sources of foreignSorghum pollen, the stigma of the male sterile inbred (female) will befertilized only with pollen from the male fertile inbred (male). Theresulting seed, born on the male sterile (female) plants is thereforehybrid and will form hybrid plants that have full fertility restored.

Genotypic Characteristics of Variety 2PTQH63

In addition to phenotypic observations, a plant can also be described oridentified by its genotype. The genotype of a plant can be characterizedthrough a genetic marker profile. Genetic marker profiles can beobtained by techniques such as Restriction Fragment Length Polymorphisms(RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily PrimedPolymerase Chain Reaction (AP-PCR), DNA Amplification Fingerprinting(DAF), Sequence Characterized Amplified Regions (SCARs), AmplifiedFragment Length Polymorphisms (AFLPs), Simple Sequence Repeats (SSRs)which are also referred to as Microsatellites, and Single NucleotidePolymorphisms (SNPs).

Particular markers used for these purposes may include any type ofmarker and marker profile which provides a means of distinguishingvarieties. A genetic marker profile can be used, for example, toidentify plants of the same variety or related varieties or to determineor validate a pedigree. In addition to being used for identification ofSorghum variety 2PTQH63, its inbred parents, and its plant parts, thegenetic marker profile is also useful in developing a locus conversionof 2PTQH63.

Methods of isolating nucleic acids from Sorghum plants and methods forperforming genetic marker profiles using SNP and SSR polymorphisms arewell known in the art. SNPs are genetic markers based on a polymorphismin a single nucleotide. A marker system based on SNPs can be highlyinformative in linkage analysis relative to other marker systems in thatmultiple alleles may be present.

A method comprising isolating nucleic acids, such as DNA, from a plant,a plant part, plant cell or a seed of the Sorghum plants disclosedherein is provided. The method can include mechanical, electrical and/orchemical disruption of the plant, plant part, plant cell or seed,contacting the disrupted plant, plant part, plant cell or seed with abuffer or solvent, to produce a solution or suspension comprisingnucleic acids, optionally contacting the nucleic acids with aprecipitating agent to precipitate the nucleic acids, optionallyextracting the nucleic acids, and optionally separating the nucleicacids such as by centrifugation or by binding to beads or a column, withsubsequent elution, or a combination thereof. If DNA is being isolated,an RNase can be included in one or more of the method steps. The nucleicacids isolated can comprise all or substantially all of the genomic DNAsequence, all or substantially all of the chromosomal DNA sequence orall or substantially all of the coding sequences (cDNA) of the plant,plant part, or plant cell from which they were isolated. The amount andtype of nucleic acids isolated may be sufficient to permit whole genomesequencing of the plant from which they were isolated or chromosomalmarker analysis of the plant from which they were isolated.

The methods can be used to produce nucleic acids from the plant, plantpart, seed or cell, which nucleic acids can be, for example, analyzed toproduce data. The data can be recorded. The nucleic acids from thedisrupted cell, the disrupted plant, plant part, plant cell or seed orthe nucleic acids following isolation or separation can be contactedwith primers and nucleotide bases, and/or a polymerase to facilitate PCRsequencing or marker analysis of the nucleic acids. In some examples,the nucleic acids produced can be sequenced or contacted with markers toproduce a genetic profile, a molecular profile, a marker profile, ahaplotype, or any combination thereof. In some examples, the geneticprofile or nucleotide sequence is recorded on a computer readablemedium. In other examples, the methods may further comprise using thenucleic acids produced from plants, plant parts, plant cells or seeds ina plant breeding program, for example in making crosses, selectionand/or advancement decisions in a breeding program. Crossing includesany type of plant breeding crossing method, including but not limited tocrosses to produce hybrids, outcrossing, selfing, backcrossing, locusconversion, introgression and the like. Favorable genotypes and ormarker profiles, optionally associated with a trait of interest, may beidentified by one or more methodologies. In some examples one or moremarkers are used, including but not limited to AFLPs, RFLPs, ASH, SSRs,SNPs, indels, padlock probes, molecular inversion probes, microarrays,sequencing, and the like. In some methods, a target nucleic acid isamplified prior to hybridization with a probe. In other cases, thetarget nucleic acid is not amplified prior to hybridization, such asmethods using molecular inversion probes. In some examples, the genotyperelated to a specific trait is monitored, while in other examples, agenome-wide evaluation including but not limited to one or more ofmarker panels, library screens, association studies, microarrays, genechips, expression studies, or sequencing such as whole-genomeresequencing and genotyping-by-sequencing (GBS) may be used. In someexamples, no target-specific probe is needed, for example by usingsequencing technologies, including but not limited to next-generationsequencing methods (see, for example, Metzker (2010) Nat Rev Genet11:31-46; and, Egan et al. (2012) Am J Bot 99:175-185) such assequencing by synthesis (e.g., Roche 454 pyrosequencing, Illumina GenomeAnalyzer, and Ion Torrent PGM or Proton systems), sequencing by ligation(e.g., SOLiD from Applied Biosystems, and Polnator system from AzcoBiotech), and single molecule sequencing (SMS or third-generationsequencing) which eliminate template amplification (e.g., Helicossystem, and PacBio RS system from Pacific BioSciences). Furthertechnologies include optical sequencing systems (e.g., Starlight fromLife Technologies), and nanopore sequencing (e.g., GridION from OxfordNanopore Technologies). Each of these may be coupled with one or moreenrichment strategies for organellar or nuclear genomes in order toreduce the complexity of the genome under investigation via PCR,hybridization, restriction enzyme, and expression methods. In someexamples, no reference genome sequence is needed in order to completethe analysis. Variety 2PTQH63 and its plant parts can be identifiedthrough a molecular marker profile. Such plant parts may be eitherdiploid or haploid. The plant part includes at least one cell of theplant from which it was obtained, such as a diploid cell, a haploid cellor a somatic cell. Also provided are plants and plant partssubstantially benefiting from the use of variety 2PTQH63 in theirdevelopment, such as variety 2PTQH63 comprising a locus conversion.

Locus Conversions of Sorghum Line 2PTQH63

Variety 2PTQH63 represents a new base genetic line into which a newlocus or trait may be introduced. Direct transformation and backcrossingrepresent two methods that can be used to accomplish such anintrogression. The term locus conversion is used to designate theproduct of such an introgression.

To select and develop a superior hybrid, it is necessary to identify andselect genetically unique individuals that occur in a segregatingpopulation. The segregating population is the result of a combination ofcrossover events plus the independent assortment of specificcombinations of alleles at many gene loci that results in specific andunique genotypes. Locus conversions can be used to add or modify one ora few traits of such a line such as yield, disease resistance, pestresistance and plant performance in varying or extreme weatherconditions.

Backcrossing can be used to improve inbred varieties and a variety whichis made using those inbreds. Backcrossing can be used to transfer aspecific desirable trait from one variety, the donor parent, to aninbred called the recurrent parent which has overall good agronomiccharacteristics yet that lacks the desirable trait. This transfer of thedesirable trait into an inbred with overall good agronomiccharacteristics can be accomplished by first crossing a recurrent parentto a donor parent (non-recurrent parent). The progeny of this cross isthen mated back to the recurrent parent followed by selection in theresultant progeny for the desired trait to be transferred from thenon-recurrent parent.

Traits may be used by those of ordinary skill in the art to characterizeprogeny. Traits are commonly evaluated at a significance level, such asa 1%, 5% or 10% significance level, when measured in plants grown in thesame environmental conditions. For example, a locus conversion of2PTQH63 may be characterized as having essentially the same phenotypictraits as 2PTQH63. The traits used for comparison may be those traitsshown in Table 1. Molecular markers can also be used during the breedingprocess for the selection of qualitative traits. For example, markerscan be used to select plants that contain the alleles of interest duringa backcrossing breeding program. The markers can also be used to selectfor the genome of the recurrent parent and against the genome of thedonor parent. Using this procedure can minimize the amount of genomefrom the donor parent that remains in the selected plants.

A locus conversion of 2PTQH63 will retain the genetic integrity of2PTQH63. For example, a locus conversion of 2PTQH63 can be developedwhen DNA sequences are introduced through backcrossing (Hallauer et al.,1988), with a parent of 2PTQH63 utilized as the recurrent parent. Bothnaturally occurring and transgenic DNA sequences may be introducedthrough backcrossing techniques. A backcross conversion may produce aplant with a locus conversion in at least one or more backcrosses,including at least 2 crosses, at least 3 crosses, at least 4 crosses, atleast crosses and the like. Molecular marker assisted breeding orselection may be utilized to reduce the number of backcrosses necessaryto achieve the backcross conversion. For example, see Openshaw, S. J. etal., Marker-assisted Selection in Backcross Breeding. In: ProceedingsSymposium of the Analysis of Molecular Data, August 1994, Crop ScienceSociety of America, Corvallis, Oreg., where it is demonstrated that abackcross conversion can be made in as few as two backcrosses. A locusconversion of 2PTQH63 can be determined through the use of a molecularprofile. A locus conversion of 2PTQH63 would have 92%, 93%, 94%, 95%,96%, 97%, 98% or 99% of the molecular markers, or molecular profile, of2PTQH63. Examples of molecular markers that could be used to determinethe molecular profile include Restriction Fragment Length Polymorphisms(RFLP), Polymerase Chain Reaction (PCR) analysis, and Simple SequenceRepeats (SSR), and Single Nucleotide Polymorphisms (SNPs).

Genetic Modification and Transformation of Sorghum Line 2PTQH63

Transgenes, genetic editing or modification and transformation methodsfacilitate engineering of the genome of plants to contain and expressheterologous genetic elements, such as foreign genetic elements,additional copies of endogenous elements, or modified versions of nativeor endogenous genetic elements in order to alter at least one trait of aplant in a specific manner. Any sequences, such as DNA, whether from adifferent species or from the same species, which have been stablyinserted into a genome using transformation are referred to hereincollectively as “transgenes” and/or “transgenic events”. Transgenes canbe moved from one genome to another using breeding techniques which mayinclude crossing, backcrossing or double haploid production. In someembodiments, a transformed variant of 2PTQH63 may comprise at least onetransgene or genetic modification but could contain at least 1, 2, 3, 4,5, 6, 7, 8, 9, 10 transgenes or genetic modifications and no more than15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, or 2 transgenes or geneticmodifications. Transformed versions of the claimed Sorghum variety2PTQH63 containing and inheriting the transgene thereof are provided. F1seed produced from 2PTQH63 are provided which are produced by crossing2PTQH63 with itself or a second plant, wherein 2PTQH63 or the secondplant comprise a transgene introduced, for example, by backcrossing orgenetic transformation and which transgene is inherited by the progenyF1 seed.

Numerous methods for plant transformation have been developed, includingbiological and physical plant transformation protocols. See, forexample, Miki et al., “Procedures for Introducing Foreign DNA intoPlants” in Methods in Plant Molecular Biology and Biotechnology, Glick,B. R. and Thompson, J. E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages67-88 and Armstrong, “The First Decade of Maize Transformation: A Reviewand Future Perspective” (Maydica 44:101-109, 1999). In addition,expression vectors and in vitro culture methods for plant cell or tissuetransformation and regeneration of plants are available. See, forexample, Gruber et al., “Vectors for Plant Transformation” in Methods inPlant Molecular Biology and Biotechnology, Glick, B. R. and Thompson, J.E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages 89-119.

In general, methods to transform, modify, edit or alter plant endogenousgenomic DNA include altering the plant native DNA sequence or apre-existing transgenic sequence including regulatory elements, codingand non-coding sequences. These methods can be used, for example, totarget nucleic acids to pre-engineered target recognition sequences inthe genome. Such pre-engineered target sequences may be introduced bygenome editing or modification. As an example, a genetically modifiedplant variety is generated using “custom” or engineered endonucleasessuch as meganucleases produced to modify plant genomes (see e.g., WO2009/114321; Gao et al. (2010) Plant Journal 1:176-187). Anothersite-directed engineering method is through the use of zinc fingerdomain recognition coupled with the restriction properties ofrestriction enzyme. See e.g., Urnov, et al., (2010) Nat Rev Genet.11(9):636-46; Shukla, et al., (2009) Nature 459 (7245):437-41. Atranscription activator-like (TAL) effector-DNA modifying enzyme (TALEor TALEN) is also used to engineer changes in plant genome. See e.g.,US20110145940, Cermak et al., (2011) Nucleic Acids Res. 39(12) and Bochet al., (2009), Science 326(5959): 1509-12. Site-specific modificationof plant genomes can also be performed using the bacterial type IICRISPR (clustered regularly interspaced short palindromic repeats)/Cas(CRISPR-associated) system. See e.g., Belhaj et al., (2013), PlantMethods 9: 39; The Cas9/guide RNA-based system allows targeted cleavageof genomic DNA guided by a customizable small noncoding RNA in plants(see e.g., WO 2015026883A1).

Plant transformation methods may involve the construction of anexpression vector. Such a vector comprises a DNA sequence that containsa gene under the control of or operatively linked to a regulatoryelement, for example a promoter. The vector may contain one or moregenes and one or more regulatory elements.

A transgenic event which has been engineered into a particular Sorghumplant using transformation techniques, could be moved into another lineusing traditional breeding techniques that are well known in the plantbreeding arts. For example, a backcrossing approach could be used tomove a transgene from a transformed Sorghum plant to an elite inbredline and the resulting progeny would comprise a transgene. Also, if aninbred line was used for the transformation then the transgenic plantscould be crossed to a different line in order to produce a transgenichybrid Sorghum plant. As used herein, “crossing” can refer to a simple Xby Y cross, or the process of backcrossing, depending on the context.Various genetic elements can be introduced into the plant genome usingtransformation. These elements include but are not limited to genes;coding sequences; inducible, constitutive, and tissue specificpromoters; enhancing sequences; and signal and targeting sequences. Forexample, see, U.S. Pat. No. 6,118,055.

With transgenic plants according to the present discovery, a foreignprotein can be produced in commercial quantities. Thus, techniques forthe selection and propagation of transformed plants, which are wellunderstood in the art, yield a plurality of transgenic plants which areharvested in a conventional manner, and a foreign protein then can beextracted from a tissue of interest or from total biomass. Proteinextraction from plant biomass can be accomplished by known methods whichare discussed, for example, by Heney and Orr, (1981) Anal. Biochem.114:92-96.

A genetic map can be generated, primarily via conventional RestrictionFragment Length Polymorphisms (RFLP), Polymerase Chain Reaction (PCR)analysis, and Simple Sequence Repeats (SSR), and Single NucleotidePolymorphisms (SNPs), which identifies the approximate chromosomallocation of the integrated DNA molecule coding for the foreign protein.For exemplary methodologies in this regard, see, Glick and Thompson,METHODS IN PLANT MOLECULAR BIOLOGY AND BIOTECHNOLOGY 269-284 (CRC Press,Boca Raton, 1993). Map information concerning chromosomal location isuseful for proprietary protection of a subject transgenic plant. Ifunauthorized propagation is undertaken and crosses made with othergermplasm, the map of the integration region can be compared to similarmaps for suspect plants, to determine if the latter have a commonparentage with the subject plant. Map comparisons would involvehybridizations, RFLP, PCR, SSR, SNP, and sequencing, all of which areconventional techniques.

Likewise, by means of the present discovery, plants can be geneticallyengineered to express various phenotypes of agronomic interest.Exemplary transgenes implicated in this regard include, but are notlimited to, those categorized below.

1. Genes that create a site for site specific DNA integration.

This includes the introduction of FRT sites that may be used in theFLP/FRT system and/or Lox sites that may be used in the Cre/Loxp system.For example, see, Lyznik, et al., (2003) “Site-Specific Recombinationfor Genetic Engineering in Plants”, Plant Cell Rep 21:925-932 and WO99/25821, which are hereby incorporated by reference. Other systems thatmay be used include the Gin recombinase of phage Mu (Maeser, et al.,1991), the Pin recombinase of E. coli (Enomoto, et al., 1983), and theR/RS system of the pSR1 plasmid (Araki, et al., 1992).

2. Genes that affect abiotic stress resistance (including but notlimited to flowering, panicle/glume and seed development, enhancement ofnitrogen utilization efficiency, altered nitrogen responsiveness,drought resistance or tolerance, cold resistance or tolerance, and saltresistance or tolerance) and increased yield under stress.

For example, see, WO 00/73475 where water use efficiency is alteredthrough alteration of malate; U.S. Pat. Nos. 5,892,009, 5,965,705,5,929,305, 5,891,859, 6,417,428, 6,664,446, 6,706,866, 6,717,034,6,801,104, WO2000060089, WO2001026459, WO2001035725, WO2001034726,WO2001035727, WO2001036444, WO2001036597, WO2001036598, WO2002015675,WO2002017430, WO2002077185, WO2002079403, WO2003013227, WO2003013228,WO2003014327, WO2004031349, WO2004076638, WO9809521 and WO9938977describing genes, including CBF genes and transcription factorseffective in mitigating the negative effects of freezing, high salinity,and drought on plants, as well as conferring other positive effects onplant phenotype; US Patent Application Publication Number 2004/0148654and WO01/36596 where abscisic acid is altered in plants resulting inimproved plant phenotype such as increased yield and/or increasedtolerance to abiotic stress; WO2000/006341, WO04/090143, U.S. patentapplication Ser.

3. Transgenes that confer or contribute to an altered graincharacteristic, such as:

-   -   A. Altered phosphorus content, for example, by the        -   (1) Introduction of a phytase-encoding gene would enhance            breakdown of phytate, adding more free phosphate to the            transformed plant. For example, see, Van Hartingsveldt, et            al., Gene 127:87 (1993), for a disclosure of the nucleotide            sequence of an Aspergillus niger phytase gene.        -   (2) Up-regulation of a gene that reduces phytate content.            For example, this could be accomplished, by cloning and then            re-introducing DNA associated with one or more of the            alleles, such as the LPA alleles, identified in mutants            characterized by low levels of phytic acid, such as in            Raboy, et al. (1990).    -   B. Altered fatty acids, for example, by down-regulation of        stearoyl-ACP desaturase to increase stearic acid content of the        plant. See Knultzon, et al., Proc. Natl. Acad. Sci. USA 89:2624        (1992).    -   C. Altered carbohydrates effected, for example, by altering a        gene for an enzyme that affects the branching pattern of starch,        a gene altering thioredoxin. (See, U.S. Pat. No. 6,531,648).        See, Shiroza, et al., (1988) J. Bacteriol 170:810 (nucleotide        sequence of Streptococcus mutans fructosyltransferase gene),        Steinmetz, et al., (1985) Mol. Gen.

No. 6,232,529 (method of        producing high oil seed by modification of starch levels (AGP)).        The fatty acid modification genes mentioned above may also be        used to affect starch content and/or composition through the        interrelationship of the starch and oil pathways.    -   D. Altered antioxidant content or composition, such as        alteration of tocopherol or tocotrienols. For example, see, U.S.        Pat. No. 6,787,683, US Patent Application Publication Number        2004/0034886 and WO 00/68393 involving the manipulation of        antioxidant levels through alteration of a phytl prenyl        transferase (ppt), WO 03/082899 through alteration of a        homogentisate geranyl geranyl transferase (hggt).    -   E.

Genes that confer male sterility        There are several methods of conferring genetic male sterility        available, such as multiple mutant genes at separate locations        within the genome that confer male sterility, as disclosed in        U.S. Pat. Nos. 4,654,465 and 4,727,219 to Brar, et al., and        chromosomal translocations as described by Patterson in U.S.        Pat. Nos. 3,861,709 and 3,710,511. In addition to these methods,        Albertsen, et al., U.S. Pat. No. 5,432,068, describes a system        of nuclear male sterility which includes: identifying a gene        which is critical to male fertility, silencing this native gene        which is critical to male fertility; removing the native        promoter from the essential male fertility gene and replacing it        with an inducible promoter; inserting this genetically        engineered gene back into the plant; and thus creating a plant        that is male sterile because the inducible promoter is not “on”        resulting in the male fertility gene not being transcribed.        Fertility is restored by inducing, or turning “on,” the        promoter, which in turn allows the gene that confers male        fertility to be transcribed.    -   A. A dominant nuclear gene, Ms(tc) controlling male sterility.        See, Elkonin, L. A., Theor. Appl. Genet. (2005) 111(7):        1377-1384.    -   B.

(A) A herbicide that inhibits the growing point or meristem, such as animidazolinone or a sulfonylurea. Exemplary genes in this category codefor mutant acetolactate synthase (ALS) and acetohydroxy acid synthase(AHAS) enzyme as described, for example, in U.S. Pat. Nos. 5,605,011;5,013,659; 5,141,870; 5,767,361; 5,731,180; 5,304,732; 4,761,373;5,331,107; 5,928,937; and 5,378,824; US Patent Publication No.20070214515, and international publication WO 96/33270.

See, for example, U.S. Pat. No. 4,940,835,which discloses the nucleotide sequence of a form of EPSPS which canconfer glyphosate tolerance. U.S. Pat. No. 5,627,061 also describesgenes encoding EPSPS enzymes. See also U.S. Pat.

Glyphosate tolerance is also imparted to plants that express a gene thatencodes a glyphosate oxido-reductase enzyme as described more fully inU.S. Pat. Nos. 5,776,760 and 5,463,175. In addition, glyphosatetolerance can be imparted to plants by the over expression of genesencoding glyphosate N-acetyltransferase. See, for example,US2004/0082770; US2005/0246798; and US2008/0234130. A DNA moleculeencoding a mutant aroA gene can be obtained under ATCC accession No.39256, and the nucleotide sequence of the mutant gene is disclosed inU.S. Pat. No. 4,769,061. European Patent Application No. 0 333 033 andU.S. Pat. No. 4,975,374 disclose nucleotide sequences of glutaminesynthetase genes which confer tolerance to herbicides such asL-phosphinothricin. The nucleotide sequence of aphosphinothricin-acetyl-transferase gene is provided in European PatentNos. 0 242 246 and 0 242 236. See also, U.S. Pat. Nos. 5,969,213;5,489,520; 5,550,318; 5,874,265; 5,919,675; 5,561,236; 5,648,477;5,646,024; 6,177,616 B1; and 5,879,903. Exemplary genes conferringresistance to phenoxy propionic acids, cyclohexanediones andcyclohexones, such as sethoxydim and haloxyfop, are the Acc1-S1, Acc1-S2and Acc1-S3 genes described by Marshall et al., Theor. Appl. Genet. 83:435 (1992).

(C) A herbicide that inhibits photosynthesis, such as a triazine (psbAand gs+ genes) and a benzonitrile (nitrilase gene) such as bromoxynil.Przibilla et al., Plant Cell 3: 169 (1991), describe the transformationof Chlamydomonas with plasmids encoding mutant psbA genes. Nucleotidesequences for nitrilase genes are disclosed in U.S. Pat. No. 4,810,648to Stalker, and DNA molecules containing these genes are available underATCC Accession Nos. 53435, 67441 and 67442. Cloning and expression ofDNA coding for a glutathione S-transferase is described by Hayes et al.,Biochem. J. 285: 173 (1992).

(D) Other genes that confer tolerance to herbicides include: a geneencoding a chimeric protein of rat cytochrome P4507A1 and yeastNADPH-cytochrome P450 oxidoreductase (Shiota et al. (1994) Plant Physiol106:17), genes for glutathione reductase and superoxide dismutase (Aonoet al. (1995) Plant Cell Physiol 36:1687, and genes for variousphosphotransferases (Datta et al. (1992) Plant Mol Biol 20:619).

(E) A herbicide that inhibits protoporphyrinogen oxidase (protox or PPO)is necessary for the production of chlorophyll, which is necessary forall plant survival.

Plant defenses are often activatedby specific interaction between the product of a disease resistance gene(R) in the plant and the product of a corresponding avirulence (Avr)gene in the pathogen. A plant variety can be transformed with clonedresistance gene to engineer plants that are resistant to specificpathogen strains.

Provided are methods of harvesting the grain of the F1 plant of variety2PTQH63 and using the grain, F2, as seed for planting. Also provided aremethods of using the seed of variety 2PTQH63, F1, as seed for planting.Embodiments include cleaning the seed, treating the seed, and/orconditioning the seed. Cleaning the seed includes removing foreigndebris such as weed seed, chaff, and non-seed plant matter from theseed. Conditioning the seed can include controlling the temperature andrate of dry down and storing seed in a controlled temperatureenvironment. Seed treatment is the application of a composition to theseed such as a coating or powder. Methods for producing a treated seedinclude the step of applying a composition to the seed or seed surface.Seeds are provided which have on the surface a composition. Someexamples of compositions are insecticides, fungicides, pesticides,antimicrobials, germination inhibitors, germination promoters,cytokinins, and nutrients. Carriers such as polymers can be used toincrease binding to the seed.

To protect and to enhance yield production and trait technologies, seedtreatment options can provide additional crop plan flexibility and costeffective control against insects, weeds and diseases. Seed material canbe treated, typically surface treated, with a composition comprisingcombinations of chemical or biological herbicides, herbicide safeners,insecticides, fungicides, germination inhibitors and enhancers,nutrients, plant growth regulators and activators, bactericides,nematicides, avicides and/or molluscicides. These compounds aretypically formulated together with further carriers, surfactants orapplication-promoting adjuvants customarily employed in the art offormulation. The coatings may be applied by impregnating propagationmaterial with a liquid formulation or by coating with a combined wet ordry formulation. Examples of the various types of compounds that may beused as seed treatments are provided in The Pesticide Manual: A WorldCompendium, C. D. S. Tomlin Ed., Published by the British CropProduction Council, which is hereby incorporated by reference.

Some seed treatments that may be used on crop seed include, but are notlimited to, one or more of abscisic acid, acibenzolar-S-methyl,avermectin, amitrol, azaconazole, azospirillum, azadirachtin,azoxystrobin, Bacillus spp. (including one or more of cereus, firmus,megaterium, pumilis, sphaericus, subtilis and/or thuringiensis),Bradyrhizobium spp. (including one or more of betae, canariense,elkanii, iriomotense, japonicum, liaoningense, pachyrhizi and/oryuanmingense), captan, carboxin, chitosan, clothianidin, copper,cyazypyr, difenoconazole, etidiazole, fipronil, fludioxonil,fluoxastrobin, fluquinconazole, flurazole, fluxofenim, harpin protein,imazalil, imidacloprid, ipconazole, isoflavenoids,lipo-chitooligosaccharide, mancozeb, manganese, maneb, mefenoxam,metalaxyl, metconazole, myclobutanil, PCNB, penflufen, Penicillium,penthiopyrad, permethrine, picoxystrobin, prothioconazole,pyraclostrobin, rynaxypyr, S-metolachlor, saponin, sedaxane, TCMTB,tebuconazole, thiabendazole, thiamethoxam, thiocarb, thiram,tolclofos-methyl, triadimenol, Trichoderma, trifloxystrobin,triticonazole and/or zinc. PCNB seed coat refers to EPA registrationnumber 00293500419, containing quintozen and terrazole. TCMTB refers to2-(thiocyanomethylthio) benzothiazole.

Seed varieties and seeds with specific transgenic traits may be testedto determine which seed treatment options and application rates maycomplement such varieties and transgenic traits in order to enhanceyield. For example, a variety with good yield potential but head smutsusceptibility may benefit from the use of a seed treatment thatprovides protection against head smut, a variety with good yieldpotential but cyst nematode susceptibility may benefit from the use of aseed treatment that provides protection against cyst nematode, and soon. Likewise, a variety encompassing a transgenic trait conferringinsect resistance may benefit from the second mode of action conferredby the seed treatment, a variety encompassing a transgenic traitconferring herbicide resistance may benefit from a seed treatment with asafener that enhances the plants resistance to that herbicide, etc.Further, the good root establishment and early emergence that resultsfrom the proper use of a seed treatment may result in more efficientnitrogen use, a better ability to withstand drought and an overallincrease in yield potential of a variety or varieties containing acertain trait when combined with a seed treatment.
